The plywood production process consisted of two steps: firstly impregnation and curing of the veneers, and secondly assembly of the panel. The adhesive used was a phenolic resin. The values obtained for shear strength were above the standard limit of rejection (1 N mm(-2)), and therefore the samples met the European requirements of plywood designed for exterior conditions. The phenolic resin improved its adhesive ability when the samples were heated for 72h at 95 degrees C. The highest shear strength for modified wood was 3.97 +/- .45 N mm(-2) at 0.8 M, 3.39 +/- 0.26 N mm(-2) at 1.3 M, and 2.35 +/- 0.23 N mm(-2) at 2.3 M, for Betula sp., Fagus sp., and Piceo sp., respectively. The samples constructed with unmodified veneers presented higher shear strengths and higher cohesive wood failures than the samples constructed with modified veneers. The possible effect of the two-steps production of the plywood is discussed. The delamination test of DMDHEU-modified Betula sp. and Fagus sp. plywood showed no open glue lines, while the samples of Picea sp. treated with the higher concentration of DMDHEU suffered delamination.

All modifications caused a substantial reduction in WU in the longitudinal, tangential and radial directions both after short (24 h) and long contact times (168, 336 h) with a saturated sponge. The water uptake coefficient (w (t) ) was reduced by approximately 71-89 % in furfurylated wood, with the higher weight percent gain (WPG) providing a slightly greater reduction. The reduction in WU was not found to depend on the NMM solid content. The NMM treatment had the maximum effect on the reduction of tangential w (t) by 80-84 % and was much smaller in the longitudinal direction (31-68 %). The treatment temperature of 195 A degrees C gave lower WU values than treatment at 210 A degrees C, and the only exception was the radial direction of Scots pine. The longitudinal w (t) of heat-treated beech represented the highest reduction by 81-89 %, while radial w (t) was less affected in both species. Sessile drop apparent contact angles for water and diidomethane and corresponding surface energies on planed tangential and radial wood surfaces revealed an increased hydrophobicity and reduced polarity of modified wood. Furfurylated and NMM modified tangential surfaces had a higher increase of apparent contact angles than the radial surfaces but this was not observed in the case of heat treatment. Heat-treated wood showed reduced wetting of surfaces only with water. Apparent contact angles did neither differ with treatment temperature nor with the NMM resin load. The disperse component of surface energy was slightly increased by 20 % maximum in modified wood, while the polar components showed a dramatic decrease by -30 to -90 % with no major differences among treatments and intensities, and between surfaces. The results provide a better understanding of the hygroscopic behaviour of modified wood, which might be useful to predict its adhesion with various polymers such as glues, coatings and paints."],["dc.identifier.doi","10.1007/s00107-015-0919-8"],["dc.identifier.isi","000359022200007"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/36236"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1436-736X"],["dc.relation.issn","0018-3768"],["dc.title","Water uptake and wetting behaviour of furfurylated, N-methylol melamine modified and heat-treated wood"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Although the basic colour of wood was slightly changed due to the modification, modified and unmodified samples did not display any colour differences after coating with translucent stains. Blocking of coated wooden substrates (degree of adhesiveness) was dependant on the type of finish system and, in a few cases, on the wood substrate. For all wood substrates, both treated and untreated, solvent-borne alkyd finish penetrated into the surface layers of the wood cells, while water-borne acrylic finishes spread only on the wood surfaces. The solvent-borne alkyd finish dried much more slowly on wood substrates than did the water-borne acrylics. Modification with mDMDHEU did not affect the drying rates of the finishes tested. The wet adhesion depended on the finish systems tested and on the pre-treatment of the wooden substrate. With regard to the pre-treatment, wet adhesion of one water-borne and the solvent-borne finish systems was significantly enhanced through precedent modification with mDMDHEU. The other two water-borne finish systems showed a higher degree of wet adhesion. This study demonstrates that modification of the wood substrate with mDMDHEU is compatible with both water-borne and solvent-borne finish systems and improves their wet adhesion on the wood surface.
